This is one real totally
unique shot and in all probability has never been photographed before. I
have discussed this image with a leading Government Marine Scientist who agrees
that this shark is ‘powering up’ with such force that the water is boiling (as
in a kettle) from the low pressure side of its tail producing the tube of
bubbles of steam beautifully captured in the following wave. This phenomenon
which is often associated with boat propellers is called cavitation. A Wonderful
combination of the dorsal fin slicing through the water, the ghostly image of
the shark below, gorgeous deep blue water and a glassy calm and beautifully
glossy ocean superbly reflecting light.
